Guide lineari (profilate) a rotaia quadrata

Ci sono due tipi di guide: guida con rotaia quadrata e guida con rotaia rotonda. Le rotaie sono nate prima, ma non forniscono la precisione offerta da componenti con guide a rotaia quadrata. Tuttavia, la guida a rotaia rotonda è la guida preferita per movimenti verticali con carichi pesanti. L'applicazione dovrebbe condizionare la scelta della guida lienare usata.

Mentre la rotaia a guida lineare quadra una volta costava molte volte più della tecnologia rotonda a causa dei requisiti di lavorazione impegnativi inerenti al design, le tecniche di fabbricazione delle nuove guide lineari e le economie di scala hanno indotto i progettisti a provare l'uso delle rotaie a guida quadrata in campi di applicazione più ampi. Le guide a rotaia profilata si possono ora trovare in molte delle stesse applicazioni che una volta erano supportate solo rotaia rotonda.

Le guide a rotaia quadrata può superare le rotaie a guida rotonda in determinate circostanze che richiedono una maggiore rigidità e maggiore compattezza in termini di capacità di carico in relazione alla dimensione. In generale, le guida a rotaia profilata offrono una maggiore capacità di carico, precisione e rigidità, e una durata più lunga.

L'assortimento di guide a rotaia profilata Thomson consiste nelle guide lineari a rulli e sfere Next Generation "Serie 500" , nelle compatte in "MicroGuide, TM" "Serie-T" leggera, e AccuMini. Si tratta di un'offerta completa di guide e carrelli in una vasta gamma di stili, formati e caratteristiche uniche prodotte in dimensioni standard di settore per l'adattamento facile nelle applicazioni esistenti o la progettazione di nuove applicazioni.

500 Series Roller Bearings

The 500 Series Roller rigidity is achieved by using the equivalent of a back-to-back bearing arrangement, complemented by special rollers that are crowned to prevent roller edge loading when misalignment is present. This results in lower elastic deformation as the load increases compared to a ball carriage or face-to-face bearing arrangement. A ball provides a single point contact area, while a roller provides a much greater line contact area. This results in a substantially higher load carrying capacity and lower wear with minimum rolling friction.

500 Series Ball Linear Guides

The 500 Series Ball Linear Guides are produced from high quality bearing steel. Almost all carriages, rails, and rolling elements are through-hardened. The end cap is constructed of a high strength, glass filled nylon with nitrile rubber seal. Stringent quality controls are in place to ensure consistency of materials from the source, allowing us to ensure that we delivery the highest quality product.

400 Series Profile Rail Linear Guide

The 400 Series Profile Rail Linear Guide is a cost effective, transport grade Profile Rail solution for cost-sensitive applications and is designed as a drop-in replacement with industry-standard envelope and hole patterns. Caged and non-caged carriages utilize the same rail design, enabling efficient use of inventory since only one rail type needs to be stocked for either carriage type.

MicroGuide Linear Guide

Thomson's MicroGuide Linear Guide is a miniature guidance system that provides corrosion resistance in certain clean room and wash down applications. MicroGuide's two track Gothic arch ball groove geometry enables single rail application. This stainless steel miniature guidance system is also ideal for small design envelope requirements in semiconductor processing equipment and medical diagnostic equipment.

T-Series Profile Rails

Thomson's T-Series is a lightweight, flexible and forgiving alternative to all-steel profile rails. This high quality product is made from aircraft aluminum alloy with hardened steel load bearing plates and ball paths and is an ideal choice for applications requiring reduced weight inertia. This aluminum guidance system uses hardened steel inserts in carriages and rails to provide a low-weight solution for critical, high performance applications.
